I2C

Grove I2C modules

The Linux kernel source has some basic IIO SYSFS interface documentation which might provide a little help for understanding reading these entries. The ELC2017 conference also had an IIO presentation.

• Digital Light Sensor

cd /sys/bus/i2c/devices/i2c-1;echo tsl2561 0x29 >new_device;watch -n0 cat 1-0029/iio\:device0/in_illuminance0_input

• Temperature & Humidity Sensor

cd /sys/bus/i2c/devices/i2c-1;echo th02 0x40 >new_device;watch -n0 cat 1-0040/iio\:device0/in_temp_raw
